Founder and CEO of Stone Real Estate, Michael Stone, said the decline in the number of new homes being started was concerning.
He added: “This well may be symptomatic of a diminishing pipeline of appetite by developers given the political climate and falling house prices in the capital in particular.
“However, regardless of our political position, the appetite for home ownership remains, and so we have no time to rest on our laurels where current performance is concerned and must act now to reverse the negative trends developing in terms of new homes being started.”
